Member of Technical Staff - Robotics Mechanical Engineer, Frontier AI & Robotics

We are seeking a Member of Technical Staff - Mechanical Engineer to lead the structural and electromechanical design of advanced high degree-of-freedom robotic systems within a frontier AI and robotics research lab. You will own the mechanical architecture of our robotics platform end-to-end: actuator selection, joint design, thermal management, cable routing, sensing integration, and structural optimization - all under the demanding constraints of a high-DoF system that must be lightweight, robust, and production-viable. This is a unique opportunity to define the physical design direction of a next-generation robotics platform from first principles.

The ideal candidate has deep experience designing complex robotic systems and scaling hardware from concept through prototyping to production. You thrive on analytical problem solving, possess strong intuition for structural and electromechanical tradeoffs, and are equally comfortable in CAD and on the shop floor. You will be the technical lead of a small team of talented mechanical engineers while collaborating closely with electrical, firmware, controls, and AI research teams to set the mechanical and structural direction of the platform.

Beyond core platform development, this role offers real latitude to push into novel territory - novel actuation methods, advanced sensor integration, or new approaches to mechatronic packaging. If you have research instincts alongside shipping discipline, you"ll find an environment that rewards both. We"re looking for someone who wants to be the technical authority on how a high-performance robot is physically built, not just a contributor to the effort.

What You Bring:

• A systems-thinking mindset with a strong grasp of cross-domain engineering tradeos.
• A bias toward action: comfortable building, testing, and iterating rapidly.
• A collaborative and communicative working style - especially in multi-disciplinary research environments.
• A passion for robotics and advancing the state of the art in intelligent, capable machines.

Key job responsibilities

• Lead mechanical design of robotic subsystems and full platforms, including structures, joints, enclosures, and mechanisms for a research environment.
• Own kinematic, dynamic, and structural analyses to guide the design and optimization of full systems and subsystems of high-DoF robots
• Specify and integrate actuators and motors for high-torque density applications in high-degree-of-freedom systems.
• Drive rapid iteration and prototyping cycles - from concept sketches through functional hardware - to accelerate learning and compress development timelines in a fast-paced R&D environment.
• Partner with the AI research team to establish simulation pipelines that enable rapid exploration of mechanical design space, informing actuator choices, structural topology, and system-level tradeoffs before committing to physical builds.
• Contribute to thermal management strategies for motors, sensors, and embedded compute hardware.
• Integrate sensors such as lidar, stereo cameras, IMUs, tactile sensors, and compute modules into compact, functional assemblies.
• Design and route cabling and wire harnesses, ensuring reliability, serviceability, and thermal/electrical integrity.
• Prototype and test mechanical systems; support hands-on builds, debug sessions, and field testing.
• Conduct root cause analysis on system-level failures or performance issues and implement design improvements.
• Apply Design for Manufacturing (DFM) and Design for Assembly (DFA) principles to transition prototypes into scalable builds (10s-100s of units).
• Collaborate with cross-functional teams in electrical engineering, controls, perception, and research to meet research and product goals.
